Flue gas desulfurization (fgd) is a waste incineration process that employs limestone slurry (CaCO 3) as a scrubber to remove SO 2 from exhaust gases, thereby reducing pollutant emissions. CaCO 3 reacted with SO 2 to form calcium sulphite (CaSO 3), which was then oxidized to form anhydrite (CaSO 4) and gypsum (CaSO 4 ⋅2H 2 O), also known as fgd sludge.
